What do you do to boost your motivation when it's running low?
I dare myself. I set all kinds of dares. "I dare you to write for ten more minutes....I dare you to read five more pages of this book you need for research....I dare you to edit today for a half hour." I can never resist a dare. And when daring doesn't work, I'm not above bribery. (Ice cream today? ONLY IF YOU WRITE FIVE PAGES.)
